![]() Video that is letterboxed before being encoded can be flagged so that the player will tell a widescreen TV to automatically expand the picture. It merely reproduces it as a standard 4:3 TV picture. All formatting done to the video prior to it being stored on the disc is transparent to the player. 4:3 video may have been formatted with letterboxing or pan & scan before being transferred to DVD. Widescreen systems either enlarge it or add black bars to the sides. It appears normally on a standard 4:3 display. Video stored in 4:3 format is not changed by the player. Widescreen 16:9 video, such as from a 16:9 video camera, can be stored on the disc in anamorphic form, meaning the picture is squeezed horizontally to fit the standard 4:3 rectangle, then unsqueezed during playback. Since all video formats (DVD, VHS, LD, broadcast, and so on) have the same number of scan lines, it's the horizontal resolution that makes the big difference in picture quality.ĭVD is specially designed to support widescreen displays. PAL has 625 total scan lines, but only about 576 to 580 are visible. (The extra lines contain sync pulses and other information, such as the Closed Captions that are encoded into line 21). ![]() The NTSC standard has 525 total scan lines, but only 480 to 483 or so are visible. DVD produces exactly 480 scan lines of active picture for NTSC and 576 for PAL. VHS has about 230 (172 widescreen) lines, broadcast TV has about 330 (248 widescreen), and laserdisc has about 425 (318 widescreen).ĭon't confuse lines of horizontal resolution (resolution along the x axis) with scan lines (resolution along the y axis). In practice, most DVD players provide about 500 lines instead of 540 because of filtering and low-quality digital-to-analog converters. Since DVD has 720 horizontal pixels (on both NTSC and PAL discs), the horizontal resolution can be calculated by dividing 720 by 1.33 (from the 4:3 aspect ratio) to get 540 lines. It's actually quite funny and nice in a way that you wish Meg Ryan still was. How is that OK?ĪFAICT, it's NOT a matted movie. 2:35 matted usually results in less vertical resolution than most DivX rips. Office Space proved to be such a hit on DVD that they actually went back and released a proper widescreen version - really so that people would buy a second copy. not worth it for movies that are only semi-popular and don't appeal to film geeks (c'mon, how many people watching French Kiss are going to care, if any of them have a widescreen TV it's probably set to zoom 4:3 content anyway to "fill the screen"). They'd have to go back and get a new transfer which would take more time and money. It's likely that way because they're using the same transfer they used for the widescreen VHS version (most every movie I've encountered that is done this way predates DVD) - this would mean that the source is matted and non-anamorphic.
